With the phone in the multi-color bootloader screen, connect it to the USB cable and run the HTC Sprint 2.17 OEM ROM package on your PC, which includes the radio and the ROM. Ignore the wording about Activesync in the ROM package. If it completes successfully, you can then boot into Windows and install the Olipro 2.40 bootloader, then install the HTC Sprint OEM 3.35 ROM package to get the newer radio, then flash a custom ROM for Cricket.
If the 2.17 ROM package install does not complete successfully, post what error message you get
